TV manufacturers are keen for users to actively use built-in services, from streaming to voice assistants. Therefore, the default settings rarely include an option to completely disable smart features. Here are the key reasons:

1. Integration with the operating system. On most modern TVs, Smart TV is not a separate module, but rather part of the firmware.
